Improvement in lamp-wicks



UNITED STATES ALBERlfi ANGELL, OF EAST ORANGE. NEW JERSEY,

asslenoa To CHARLES E A. HINRIOHS, OF BROOKLYN, NEW YORK IMPROVEMENT 'INLAMP-WICKS.

lspecification forming part of Letters Patent No. 188,036, dated October10, 1876; application filed May 24, 1876;

arincipal ingredient of which is mineral wool, .hich is mixed with anysuita e re rectory celneut such as a solution of ii uid' ass to arm aplastic mass, which can he molded or otherwise brought into the requiredform. If

desired, asbestus or other refractory fibrous material ,may added to themineral wool. The material which forms the principal ingredient of mylamp-wick, and which is termed mineral wool, is obtained by causing ablast or'jet of steam or air to impinge upon the surface of molten slawhich is thereby blown into filaments producing the material desired.This material forms an article of commerce,

and it has absorbent properties similar to those of fibrous materialsobtainedfrom auimal or vegetable substances, while at the same time saidmineral wool is practically non-combustible, or at least capable ofresisting very high temperature without undergoing any change in itsnature.

In order to produce lamp-wicks from this mineral wool, I mix the s mewith a refractory cement, such as a'solution of soluble lass in theproper proportion to form a p as no mass, which can be pressed, molded,or rolled into the required'form or shape,

In practice, Ivprefer to make my non-combustible lamp-wicks in the formof short heads which fit the mouth of the wick-tube, and which rest upona packingof cotton or other fibrous material, by means of which theburning fluid is raised to the non-combustible head. If desired,however, my refractory wick may be made of suificient length to extendthrough the wick-tube into the oil-cistern.

In producing the compound for my refractory wick I sometimes mix withthe mineral wool some asbestns but such is not essential for the successof the result desired.

What -I claim as new, and desire to secure by Letters Batent, is-

A non-combustible lamp-wick, made of mineral wool and mixed with arefractory cement, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 22d day of May, 1876.
